A(2, 4), B(3, 3), C(6, 4), D(5, 6)
B.
A(-1, 1), B(2, 2), C(5, 1), D(4, 1)
C.
A(-5, -2), B(-3, 3), C(3, 5), D(1, 0)
D.
A(-1, 2), B(1, 3), C(5, 3), D(1, 1)

yes. we do proportions in probabilities.

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
